The below graph shows the average semi-detached house price in the Horsham local authority area over time, sourced from the HPI. The three 10 SOUTHDOWN TERRACE sales between May 2005 and January 2021 have been plotted on the graph. A line has been extrapolated to show what the value of the property might have been over time, following each sale, had it maintained the same margin above or below the HPI (as a percentage). For example, the April 2010 sale was for 12% below the HPI. So the extrapolation line tracks at 12% below the HPI over time, until the January 2021 sale, where it rises to 2% above the HPI. The line then continues to track at 2% above the HPI.

10 SOUTHDOWN TERRACE might now be worth an estimated £490,282.
This is based on house price inflation of 24.6%, between January 2021 and August 2025, for semi-detached houses, in the Horsham local authority area, as calculated by the Office for National Statistics and published in their UK House Price Index (HPI).
The 24.6% inflationary increase is applied to the most recent sale price for 10 SOUTHDOWN TERRACE of £393,500 on 29th January 2021. For the value to have increased from £393,500 to £490,282 over the three years and five months to August 2025, the following assumptions must hold true:
